1.1.2, still no GPU acceleration?!

[WFUJay]

Using Win 7 x64 Ultimate, VLC 1.1.2, ATI HD 5850 + Catalyst 10.7, and GPU acceleration checked under codec options. Playback of a 1080p x264 Level 4.1 encoded Bluray mkv rip still being processed by the CPU. My i7 handles it fine and playback is smooth, but I'd still like to get the GPU accel working and for the life of me I can't. Didn't work in 1.1.1 either.

Any ideas?

There is no support for ATI as they have yet to release Adaquit Drivers Or so says the dev team.
To be honest I can understand this preaty easy from my experience the ATI drivers have been Preaty messed up the last cuople years

This article seems to refute your comment. Anyway, my drivers work perfectly fine in everything else and 10.7 is supposed to support GPU accel with VLC so what gives?

Open Tools -> Messages (set Verbosity to 2) before playback. It will complain if something is broken acceleration wise.

Did you activate the option for GPU ?

Did this, no complaints.

Did you activate the option for GPU ?

If you're referring to the "Accelerated video output (Overlay)" option in the video tab, yes, it's enabled. "Use GPU acceleration" is also enabled in the Input & Codecs tab. Nothing works.

Could you paste your messages here?

Could you paste your messages here?

Sure. How exactly would I do that? The message box is empty. I'm guessing you just click the little arrow up twice on the bottom left to change verbosity level to 2 and then click close. Did that, then played some movies and the message box was still empty. I'm only assuming that I did this correctly though.

[VLC_help]

You have to open the message dialog before you start playback.

Didn't want to clutter the forum so I pasted my messages to pastebin. Here's the link:

Ah I see that now. Well the message is clearly wrong, because there is 0% activity on the GPU during playback and I get small 1-5% CPU spikes still. There's also minor skips and stutters with GPU decoding option enabled, while it's perfectly smooth without the option checked. Oh well, I guess that's why it's warned as experimental. Hopefully Videolan and ATI can get the issues sorted. Thanks for the help.

It is kind of hard to fix anything when there isn't any clue what is causing the issues.

Use DxVAChecker to see if the GPU is used.
